As noted elsewhere, you could do that by building query strings and
EXECUTE'ing them ... but you really ought to rethink your table layout,
instead. The SQL-ish way to do this is to combine the tables into one
big table with an extra key column that stores whatever condition
distinguished the smaller tables in your mind.
